I opened the Mozilla mail and the Vim is not launched when composing a message.

When Viewing the page source or edit textarea, it reports an error: temporary directory c:\windows\temp does not exist.What the heck is this? it certainly does not exist on any PCs which do not have windows98 installed, neither does it exist on PCs which do not have the system installed on drive c:

The 'standard' temp directory should be %systemdrive%\winnt\temp. While user may specify their preference of temp directory in environment variable %temp%.

Note that mozillaFB plugin uninstall is still buggy, and that is why I only have one plugin installed.

To remove firebird plugin, I guess the best way for now is to wait for official release of Firebird 0.7 and install from the beginning. You can also try grep "mozex" in your profile directory and edit one by one. I believe future Firebird will have a solid uninstallation feature.

My temp directory is "C:\temp", so that's what I entered in the "Directory for temporary files" field.
Vim is located at "C:\Program Files\Vim\vim62\gvim.exe" on my system. However, mozex isn't handling its input in a very graceful way yet. Thus, spaces trip it up. The solution (which can be found on the Mozex site) is to use DOS short filenames. Thus the path becomes "C:\Progra~1\Vim\vim62\gvim.exe". We also have to pass an argument to vim so that it knows what to edit. "%t" is the argument for editing source and textareas so the input for both fields is "C:\Progra~1\Vim\vim62\gvim.exe %t".

I don't think you can use Vim for mail, as the mail function passes many more options than the body text. Check Mozex's argument list though ( http://mozex.mozdev.org/arguments.html ). I'm not a vim hacker, just a vim user. Perhaps someone with more experience could get vim to edit e-mails.

It works for me: Mozilla 1.6 on Linux (Fedora Core 2). I am using it now. Remember to click in text area after :w from vim!

I'm just trying to shamelessly drag your attention to http://mozex.mozdev.org again. I adopted mozex plugin and I'm continuing it's development. All the installation (and de-installation) issues for any mozilla based browser should be fixed. And there's much more new things (start external editor by hotkey, nice configuration dialog, utf-8 editing and more). Just be sure to install latest development version.

Vim starts up fine for me, when hitting the hotkey. But when I close it again, the text is not taken to the input box.

I'm running Vim 7.0 on Gentoo and use 'gnome-terminal -e "vim %t"' as the command in Mozex 1.9.3.

Hey, if Mozex does not work for you, you can try Viewsourcewith extension, it works fine for me with gvim (although it does not seem to work to include "xterm -e vim".
In Thunderbird I use "External Editor" extension, which works fine, too. Actually I only do this because I am to lazy to switch to Mutt, which may be way cooler than Thunderbird, but might be a pain in the ass to configure for the first time.
